patch 9.1.0223: code duplication in loop to add active text properties Commit: https://github.com/vim/vim/commit/1134fdd1b369119d0d6992e3120bb5f7c788b697 Author: Dylan Thacker-Smith <dylan.ah.smith@gmail.com> Date: Thu Mar 28 11:49:46 2024 +0100 patch 9.1.0223: code duplication in loop to add active text properties Problem: There are two dense conditions with duplication that needs to be kept in sync between the while loop break condition and the condition to skip certain text properties. Solution: Refactor the loop by moving while loop conditions into the body of the while loop so they can be shared with skip conditions. `break` and an `active` variable are used to handle the outcome of these merged conditions.
